ABSTRACT:
A frozen or refrigerated precooked meal formed from a number of food components is packaged in a compartmented tray which is transparent to radiant energy such as that from microwave or infrared energy sources. Each of the tray compartments is defined by ridges and side walls formed integrally with the tray and the different component foods of the meal are disposed within selected different tray compartments. A radiation transparent film is secured over the tray and is bonded to the upper edge of the tray side wall and ridges to seal each compartment. Selected areas of the seals between the film and portions of the ridges and/or tray side walls are weakened so that they may rupture in response to excessive water vapor pressure build up to enable the water vapor to escape. The sealed food tray may be placed in a specially formed shielding box which controls the quantity of radiation to which each of the food components are exposed within a given time.
